Application May 29, 1937, Serial No. 145,423

3 Claims.

My present invention relates to a shirred on the back side, rendering it difficult of attachment. My present invention has as its object the provision of a puckered cloth or trimming which shall have (1) a relatively smooth back surface enabling easy and snug attachment to the article or material to be trimmed, and (2) anespecially attractive puckered or gathered upper or front side.

Briefly, in carrying into effect my present invention, a series of. cords are sandwiched between two strips of cloth. These strips and the cords are run through a knitting machine in such a way, as will be explained in greater detail later, as to produce a trimming or fabric in which one side is shirred or gathered and the other is essentially smooth, especially suitable as a base or attaching surface. Attention is directed to the fact that the sandwich should be knitted, for if it is run through an ordinary sewing machine both sides will be puckered or both sides will be smooth.

In the accompanying drawing, which is typical of my invention, Figure 1 is a perspective front view of trimming made in accordance with my invention and illustrates the front puckered, shirred or gathered surface of my trimming or fabric, Figure 2 is a rear elevational view thereof, and Figure 3 is a side diagrammatic view of knitting apparatus for manufacturing my im- 4 proved fabric.

together over the cords i4,- EG, i8, 20, 22, 2d,

' and 2B. After knitting the surface 2 presents a pleated, ruffled, gathered or puckered front surface as shown in section K, Figure 1, and an essentially-or substantially smooth rear, back or bottom attaching surface as shown in Figure 2.

In Figure 3, I have diagrammatically illustrated a side view of apparatus and the way in which my improved trimming is made. The folded strip 2, 4, B of Figure 1 is guided through a suitable flattened guiding cylinder 30 over a fixed guide 32. Similarly, the parallel cords I4 to 26 inclusive, or any suitable filling material, is fed vertically over the fixed guide or stop or abutment 32. A separate cylindrical guide 35 foreach of the cords may be provided if delsired. 'Ihe folded backing strip 8, I0, l2 is also fed over the abutment 32 through a suitable flattened cylindrical guide 34.

A bank of eight knitting needles ls diagrammatically illustrated in side view at 36 and the thread, which is knitted through the front and back of the strip, is diagrammatically illustrated at 3,8. Suitable rollers for the strips and cords and suitable weights for tensioning the same may be provided, as, found desirable.

As the needles 36 pass through the material, the side of the material nearest the thread 38 appears puckered, whereas the other strip 8, l0, l2 is smooth or continuous, as shown in Figure 2. In short, the front of the .stitch has the shirr and the back a smooth face. The pleating or shirr may,1 be varied by varying the tension on the cloth by varying the distance between the guiding tubes or cylinders 30, 34 and the abutment 32 or by varying the angle between the flattened cylinders 30, 34. The greater the angle the greater the pleating, etc. I have used successfully for the manufacture of this material a so-called Ruf machine in which the speed of the rollers feeding and drawing the strips and cords through the apparatus controls the length of the stitches.

Although I am not fully certain why the shirr .appears on one side and not upon the other, it is my belief that as the needles 36 pass through the strip 2, 4, 6, the strip is moved back on itself. slightly inthe general direction of guide 30 and then as the needle is pulled through again the cloth does not have time to straighten out before the stitches are completed.

Obviously; the strips may be made of any width and any number of cords may be employed, as found desirable. The strips 2, 4, 6 and 8, l0, i2 may be made of any suitable material such as cotton or crepe acetate.' The cords may be ofcotton or they may be replaced by cotton lling. The front and back strips 2, 4, 6 and 8, l0, l2 maybe of the same material or different materials.

I-Iaving thus described my invention, what I claim. is:

1. A trimming or the like comprising a series of parallel cords, and a. pair of 'cloth strips attached to said cords, one of said strips being essentially puekered and the other essentially smooth.

2. A trimming or the like having a shirred front surface and a. smooth rear surface, comprising a series of cords and a pair of cloth strips knitted together over said cords.

3. A composite strip comprising two strips of cloth whose edges are folded inwardly and whose inwardly folded edges face one another, a series of parallel cords or lling material between said strips, said strips being knitted together, the knitting being effected at the edges of the strip and intermediate the parallel cords.
